{- Simple example

This example is intended to be as simple as possible, but containing the most significant parts.

The Overloaded Strings language extension is quite handy because it allows you to write text without
using 'fromString' everywhere.

-- By executing 'execLaTeXT' you run the 'LaTeXT' monad and make a 'LaTeX' value as output.
-- With 'renderFile' you render it to 'Text' and write it in a file.

-- It's a good idea to separate the preamble of the body.
